Web pages may implement messages that indicate successful operations. This differs from the information that appears in the feedback panel. An Operation Succeeded message appears in the page format.
<ul class = "messages">    
  <li>    
    <wicket:message key = "[successmsgkey]" />    
  </li>    
</ul>
Success messages should appear after breadcrumbs and help text, but before any related data or other page content.
